The problem of obtaining data on the users of the applications has been present from the beginning of the existence of personal computers. In the past, the information was gained mainly by means of surveys and analyses, but now new methods have been developed. We will present why new methods perform better. Demonstration of the new methods will be presented with analysis of the use and operation of the current most popular services – Google Analytics and Flurry Analytics. During the analysis of the current solution, we found some weaknesses. However, with developing our own system, we can eliminate these weaknesses. To develop our own system, we used more advanced technologies which enabled us to develop a simpler system and its scalability. Our system was tested on a test application. With the data collected, we made proposals for its improvement. Final result of the work is a comprehensive system for collecting and processing of the data on users of any application.
